Hi,
I am totally new to this site and am hoping someone can advise me as to the possible cause and steps to rectify the following?
I have a room with two wall lights both operated by two dimmer switches.
A few days ago when I switched on the lights, one light made a buzzing noise and then both went out. The fuse on the CU did not blow.
I have removed the switches and replaced both with just 1 gang 2 way switches, but now after rewiring, as soon as I replace the fuse in the CU and with both switches off the lights are on and each time I press the switch the fuse blows.
I have double checked the wiring to the switches, which was as the dimmers and the various wiring diagrams for two way switching on this site. I have also looked at the cables behind the light fittings which are the old colours but seem OK, no burning etc.
The wiring is as follows 1 wall light has 3 twin and earth cables. of which 3 reds connected together, 3 earths connected together and to earth on light fitting, 2 blacks connected together and connected to blue on light fitting and 1 black connected to brown on light fitting. On the opposing wall I have a single twin and earth correctly connected straight into light fitting.
Switch 1 has two cables twin and earth and 3 core and earth. red from T&E and red from 3 core connected to L1, black from T&E and black from 3 core connected to L2. Yellow from 3 core to common.
Switch 2 has a single 3 core & earth cable, red to L1, black to L2 and yellow to common.
I have tested both switches with a simple tester and I am getting 230volts at all three terminals in switch 1 with the switches in the off position and the light on, at switch 2 I am getting about 110volts!
Any suggestions, advice would be most welcome.
